The difference between SMT, COB and COG liquid crystal modules



The difference between SMT, COB, TAB, COG LCD modules


SMT: high reliability, strong anti-vibration ability, low solder joint defect rate. COB: On-board chip package is one of the bare chip mounting technologies. The semiconductor chip is placed on the printed circuit board. The electrical connection between the chip and the substrate is realized by the wire stitching method. The electrical connection between the chip and the substrate is realized by the wire stitching method. And covered with resin to ensure reliability. Although COB is the simplest bare die attach technology, its packaging density is far less than TAB and flip chip bonding technology. COG: COG is the abbreviation of chip on glass, that is, the chip is directly bonded to the glass. This type of installation can greatly reduce the size of the LCD module, and is easy to mass-produce. It is suitable for LCDs of consumer electronic products, such as mobile phones, PDAs and other portable products. This installation method is driven by IC manufacturers. It will be the main connection method between IC and LCD in the future.

Magnetic Light

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting

Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.

While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
